CAP SPINNING FRAME.

Application filed September 14,*1922. Serial No. 588,244. 'i

To all whom t may concern.'

Be it known that we, JOSEPH SHAW GAUNT, residing at 6 Cromford Court, Marketv Street, Manchester, England, and HARRY DYSON, residing at 67 May Street, Crosland Moor, Huddersfield, England, both British subjects, have invented certain new and useful Improvements in Cap Spinning Frames, of which the following is a specification.

This invention relates to the spindle mechanism of cap spinning frames and the chief objects are, to reduce the power required for driving the machine, to enable the revolving parts to be sufficiently lubricated without danger of the lubricant soiling the yarn, to enable the Speed of spinning to be increased, and to provide amounting for the spindles that support the caps whereby the runningof the mechanism is facilitated and undue vibration is avoided.

With these objects in view, the usual rotating tube carrying the bobbin and the whorl by which the said tube is rotated, are, according to this invention, mounted independently of, but co-axially with, the spindle by which the cap is carried; the said tube is formed with its internal diameter slightly larger thanthe diameter of the spindle, so that it rotates clear ofthe latter, and it may extend downward tov provide means whereby it is rotatably mounted in the lifting rail; this mounting is effected by means of ball bearings' arranged between the upper and lower portions of a bolster mounted in the lifting rail or plate and the Said downward extension of the tube, which may pass through the bolster;` and between Ythe upper and lower ball'beaiings the whorl may be mounted upon the tube. The'usual rigid fastening at the foot of the cap-carry ing spindle is dispensed with and lthe spindle is mounted in the lower or spindle rail sufficiently loosely to permit of a slight degreel of play in its support, thus allowing the spindle to accommodate itself to any irregularities in the lifting-rail movement and also simplifying thel setting of the spindle by avoiding fine adjustments.l

The invention will now'be described with reference to the accompanying drawings in which, i

Figure l is an elevation, v

Figure l is a sectional elevation of a moflaton of the spindle mounting, and

Figure 2 is a sectional side elevation.

Like letters indicate like parts throughout the drawings.

A is a spindle carrying a cap A1 and having an enlargement 2 formed or provided at its lower end; the enlargement 2 is fitted loosely within a recess 3 in a rail 4 and is prevented from being withdrawn during doffing by a ring or washer 6 sunk into the rail 4; and the lower face of the enlargement 2'is made Slightly convex at 7, as shown, anda screw 5 constitutes an adjustable support, which is secured in position by lock nuts 8.

The modified spindle mounting of Fig. la Vcomprises a rail 4 having a recess 3 therein. A screw 5 is received in the rece-Ss and affords an adjustable support for a conveXed end 7 on the spindle A, a lock nut 8 holding the screw 5 in adjusted position.

C is a lifter rail or plate, and B is a bolster comprising upper and lower members B1 and B2 bored to receive the outer rings b1 b2 of upper and lower ball bearings, the inner rings'3 b4 of which are mounted upon a bobbin tube D. Between the upper and lower ball bearings, and also between the upper and lower members B1 B2 of the bolster B, the kwhorl G is mounted. For the purpose of clamping the outer ball race rings b1 b2 within the bolster, the members B1 B2 thereof are divided as shown at BX and are clamped'closely in contact with the said rings b1 bzfby screws o* passing through lugs b9..

E is a bobbin mounted upon a bobbiu flange F by means of the usual lugs F1 t this flange may be shrunkor otherwise secured to the tube D and forms an abutment against which the inner ball rings b3 b4 and the whorl Gr; are clamped by means of a nut ,fwhich is screwed upon the lower end ofthe tube D. the inner ball rings 3 b* being respectively in contact with the upper and lower bosses of the whorl Gr, as shown at Figure 2. The edge of the flangek Fis curved downward as at f to afford protection against dust and fluff to the bearing in the upper member B1 of the bolster.

The outer ring b1 of the upper bearing' is held within the recess in the member Bl of the bolster B by a divided ring or wire Spring b5, which engages with an annular groove B5 in the said member B1. l

Between the bobbin flange F and the up per bearing there is arranged an annular cover bs for the latter, and h6 is a corresponding cover ring for the lower ball bearing: the cover 228 is shown resting upon the upper member B1 of the bolster, but it may be dispensed with in some cases in view of the protection given by the downwardly bent flange 7 described above; the cover 5G is pressed into a recess in the lower member B2 of the said bolster. Further, beneath the upper ball bearingv there is provided an annular ring 67, which is pressed upward into the recess in the lower member B2.

The bolster B is formed on its under side with a boss B7 having a hole S through which the spindle A passes. The said boss BT is fitted into a corresponding recess in the upper face of the lifting rail C, which is also bored to permit the spindle A to pass through, the holes bored in the boss B7 and in the lifting rail are made a sliding fit upon the spindle and thus serve as supports for the latter. A washer C2 of felt or other suitable material may be interposed between the lower face of the bolster and the bottom of the recess in the lifting rail. The said washer should closely embrace the spindle thus preventingI undue leakage of lubricant from the lower bearing.

The bolsters B are secured to the lifting rail by means of screws passingl through. holes in lugs (not shown in the drawings on the lower member B2.

lVhat we claim and desire to secure by Letters Patent is l.
